A) Number of Z disc
B) Number of desmosomes
C) Number of slow Ca+2 channels

Ischemia is the cell and tissue damage which results from the lack of the proper blood supply in the heart. Due to improper blood supply there is a lack of oxygen in the heart.

The damaged tissue is normally being replaced by the scar tissue which is quite different from the normal tissue and its basic structure is also not the same.

The scarred tissue lacks the pumps and channels which is necessary to establish the resting potential.
